Vintage Art Deco style unusual smoky quartz colour aurora borealis Austrian crystal riviere necklace, triple strand, bezel set, open backed

Stunning three strand mid-century Art Deco style necklace with bezel set smoky coloured aurora borealis crystals set in silver tone, with open backs allowing the light to stream through and pick up the rainbow colours of the crystal. This is a gorgeous piece. The choker length is adjustable using the hook fastener and extender chain, and it goes up to 16 inches for the strand directly around the neck. These crystals are a really unusual smoky quartz colour - I haven't seen it before in this style of necklace. It is in very good vintage condition - only very minor wear.
